Tree Mapping


The Dublin Tree map initiative is a health check on our city’s urban forest, a chance to identify what trees we have and learn how important they are. Let’s get mapping our valuable tree canopy so we can work towards a green and sustainable Dublin.

Mapping Green Dublin is proud to share the citizen science Dublin Tree Map initiative with its partners Common Ground, Artist Seoidín O’Sullivan, Dublin City Council, UCD Geography, Connect the Dots and CURIO.  The Dublin Tree Map initiative aims to map the tree species we have throughout Dublin city, and identify where the deficits are. 

Thanks to UCD Geography’s Gerald Mills and Tine Ningal, Mapping Green Dublin has mapped all the trees across Dublin and they are now uploaded now onto the CURIO website. On RTE Drivetime on May 13th Professor Gerald Mills described the tree database as a ‘fundamental part of the geography of our city. Mapping the trees establishes a benchmark for plans to make our neighbourhoods greener and improve the outdoor environment’  you can listen to his extended interview here. 

Seoidín also talked to Philip Boucher Hayes on RTE Drivetime about why her art project PLOTS responded to the 2km Covid 19 distance limit ‘The 2 km radius means we are all currently hyper local. We are walking and accessing our neighbourhoods daily and this provides an opportunity to see deficits in our communities around green infrastructure. Where can we improve cycle routes , pedestrian and wheel chair/ buggy access? How and where can we improve biodiversity and planting?’ 


Identifying Dublin’s tree species type is valuable as it helps the city to plan and cope with changing pollution and climate needs. We need a greater number of different tree species across the city and gathering that information about our urban trees is important for future resilience and biodiversity.  Can you identify trees in your street or place of work in Dublin? Use the CURIO. App. to map our city trees.  We’ve uploaded a video how to use the Curio app video below.
